FIG. 12 is a perspective view showing a state in which the lamp device is attached to the socket body arranged at the protruding position of the socket device, and FIG. 13 is a perspective view showing the state of the socket device. It is a perspective view which shows the state which moved the socket main body to the accommodation position.

The socket device 13 includes a socket support 71 attached to the flat plate portion 17 of the instrument main body 12, and a socket device main body 21 supported so as to be movable in the vertical direction with respect to the socket support 71.

The socket support 71 is made of, for example, metal and is opened downward, and the socket device main body 21 is fitted therein so as to be movable in the vertical direction. In other words, the socket support body 71 supports the socket device main body 21 so as to be movable between a storage position where the socket device body 21 is stored in the socket support body 71 and a protruding position where the socket support body 71 protrudes downward.

A spring 72 is disposed between the socket support 71 and the socket device main body 21 as a biasing means for biasing the socket device main body 21 toward the protruding position. The socket support 71 projects from the socket device main body 21. A stopper (not shown) that restricts the protrusion at the position is provided.

Between the socket support 71 and the socket device main body 21, there is provided a locking means (not shown) for locking the socket device main body 21 in the storage position. This locking means, such as a push button switch, pushes the socket device body 21 from the protruding position to the storage position by the lamp device 14 and moves it to lock the socket device body 21 in the storage position. Further, the lamp device 14 is configured to allow the lamp device 14 to be unlocked by slightly pushing up the socket device body 21 and to allow the socket device body 21 to be lowered from the storage position to the protruding position. Such a locking means can be realized by a spring for biasing the socket support 71 in the socket support 71 and a cam mechanism for regulating the rotation angle, but other well-known mechanisms may be used. .

A plurality of cylindrical ribs 73 project from the socket support 71 in the vertical direction and are semicircular in cross section that engage with the ribs 73 at a plurality of locations on the outer periphery of the socket device body 21. 74 are formed along the vertical direction, and a locking member 75 is disposed in these groove portions 74 so as to be able to advance and retract. The lock member 75 moves forward and backward in the groove portion 74 in conjunction with the turning operation of the lamp device 14 when the lamp device 14 is attached to and detached from the socket device main body 21 held at the protruding position. It can be configured by a cam mechanism that contacts 44. The lock member 75 enters the groove 74 when the lamp device 14 is not attached to the socket device main body 21 located at the protruding position, and the rib 75 when the socket device main body 21 attempts to move from the protruding position to the storage position. 73, the movement of the socket device 21 is restricted, and when the lamp device 14 is connected to the socket device body 21 located at the protruding position, the socket device body 21 is retracted from the groove 74, and the socket device body 21 is moved from the protruding position to the retracted position.

Therefore, the rib 73, the groove 74, the lock member 75, and the like allow the socket device body 21 to which the lamp device 14 is mounted to move between the protruding position and the storage position, and the lamp device 14 is mounted. Locking means 76 is configured to restrict the movement of the socket device main body 21 not being moved from the protruding position to the storage position.

In a state where the socket device main body 21 is moved to the storage position, the rib 73 is located in a region where the lock member 75 enters the groove portion 74, and the lock member 75 cannot enter the groove portion 74. The device 14 is in a state where it cannot be rotated in the direction to remove it from the socket device main body 21. Therefore, the rib 73, the groove 74, the lock member 75, and the like constitute a lamp device holding means 77 that restricts the lamp device 14 from being detached from the socket device main body 21 moved to the storage position.

The socket support 71 is provided with a heat conducting member 78 for connecting the lamp device 14 so that the lamp device 14 can conduct heat by moving the socket device main body 21 to which the lamp device 14 is mounted to the storage position.

9 and 11, the socket device main body 21 of the socket device 13 to which the lamp device 14 is not mounted is in a protruding position protruding downward with respect to the socket support 71, and the instrument main body 12 Is located close to the opening 19 side, and is held by the spring 72 at the protruding position.

To attach the lamp device 14 to the socket device 13, the lamp device 14 is raised so that each lamp pin 44 of the lamp device 14 is inserted in accordance with the enlarged diameter portion 26 of each connection hole 25 of the socket device main body 21. At this time, even if the lamp pin 44 of the lamp device 14 is not aligned with the enlarged diameter portion 26 of each connection hole 25 of the socket device main body 21 and the socket device main body 21 is pushed up by the lamp pin 44, the lock member 75 remains at the tip of the rib 73. It is possible to prevent the lamp device 14 from becoming difficult to attach due to the contact with the surface and the socket device body 21 moving to the upper storage position.

After each lamp pin 44 of the lamp device 14 is inserted into the enlarged diameter portion 26 of each connection hole 25 of the socket device main body 21, the lamp device 14 is rotated in the mounting direction as shown in FIG. Mounted on the apparatus main body 21.

Thus, when the lamp device 14 is attached to the socket device main body 21, the socket device main body 21 is in the protruding position and is close to the opening 19 side of the lower surface of the instrument main body 12. There is a space for a finger to enter between the peripheral part of the lamp device 14 to be attached to the device body 21 and the reflector 18 of the fixture body 12, and the lamp device 14 can be held by hand and easily attached to the socket device body 21. .

Rotation of the lamp device 14 in the mounting direction allows the lock member 75 to be retracted from the groove portion 74 in conjunction with the rotation, and allow the socket device body 21 to move to the storage position.

After the lamp device 14 is mounted on the socket device body 21, as shown in FIGS. 10 and 13, by pushing up the lamp device 14, the socket device body 21 is pushed up to the storage position, and the lamp device 14 is moved into the appliance body 12. It can be held at a predetermined mounting position. The socket device body 21 moved to the storage position is locked by the locking means.

When the socket device main body 21 to which the lamp device 14 is mounted moves to the storage position, the base portion 38 of the lamp device 14 comes into surface contact with the heat conducting member 78 and is in close contact therewith. It becomes.

When the LED 35 of the lamp device 14 is turned on, heat is generated. However, since the base portion 38 of the lamp device 14 is in close contact with the heat conducting member 78, the heat generated from the lamp device 14 is transmitted through the heat conducting member 78. Heat can be efficiently conducted to the fixture body 12, and the heat dissipation of the lamp device 14 can be improved.

When the socket device main body 21 is in the storage position, the rib 73 is located in a region where the lock member 75 in the groove portion 74 enters, and the lock member 75 cannot enter the groove portion 74, and the lamp device interlocks with the lock member 75. 14 cannot be rotated in the direction to remove it from the socket device main body 21.

On the other hand, when the lamp device 14 is removed, the socket device body 21 and the lamp device 14 are urged together with the lamp device 14 by urging by the spring 72 by slightly pushing up the lamp device 14 located in the storage position and releasing the lock by the locking means.

When the socket device main body 21 is lowered to the protruding position, the lamp device 14 is removed from the connection hole 25 of the socket device main body 21 by removing the lamp pin 44 of the lamp device 14 by rotating the lamp device 14 in the removing direction and then lowering the lamp device 14. It can be removed from the socket device main body 21.

When the socket device main body 21 is lowered to the protruding position, the position of the lock member 75 of the socket device main body 21 is moved downward from the rib 73. Therefore, the lock member 75 is grooved in conjunction with the rotation of the lamp device 14 in the removal direction. 74 enters the state where the socket device main body 21 is restricted from moving to the storage position.

As described above, according to the socket device 13, the socket device main body 21 is movable between the storage position stored on the socket support 71 side and the protruding position protruding from the socket support 71 side. Even when used in a lighting fixture, the socket device main body 21 is moved to the protruding position with respect to the socket support 71 attached to the fixture main body 12 side, so that the side surface of the lamp device 14 can be gripped and easily attached and detached. .

Further, since the lamp device holding means 77 restricts the lamp device 14 from being detached from the socket device main body 21 that has moved to the storage position, the lamp device 14 attached to the socket device 13 can be prevented from being detached, and the lamp device can be prevented from being detached. When 14 is removed, the socket device 13 can always be held in the protruding position, and the lamp device 14 can be easily attached.

Next, FIG. 14 shows a sixth embodiment, and FIG. 14 is a sectional view of the lighting fixture.

The lamp device main body 34 of the lamp device 14 is entirely formed of a metal such as aluminum having excellent heat dissipation, and is made of, for example, aluminum die casting, and a base-side metal component 81 and a substrate constituting the base portion 38.

That is, the light emitting module substrate 50 is attached in close contact with the substrate mounting portion 39 of the metal lamp device main body 34, and the screw 85 which is a heat conduction connecting means is capable of heat conduction from the substrate mounting portion 39 side to the base portion 38 side. Since it is connected, the heat generated by the LED 35 can be efficiently conducted to the board mounting portion 39 and also efficiently conducted from the board mounting portion 39 side to the base portion 38 side. The heat conducted to the base part 38 is thermally conducted to the instrument body 12 with which the base part 38 contacts, and can be efficiently radiated.

A plurality of slits that divide the reflector plate 18 in the circumferential direction are provided in the reflector plate 18 so that the small pieces of the divided reflector plate 18 have elasticity, and the outer periphery of the lamp device main body 34 83 and the reflector 18 may be configured to be in close contact with each other. Furthermore, a metal spring member that is in close contact with the outer peripheral portion 83 of the lamp device main body 34 may be separately received and thermally conducted.

Next, FIG. 15 shows a seventh embodiment, and FIG. 15 is a sectional view of a lighting fixture.

The screw unit 94 is used as a heat conduction connecting means for connecting the lamp device main body 34 from the substrate mounting part 39 side to the base part 38 side so as to allow heat conduction. That is, a screw portion 95 is formed on the outer peripheral portion 83 of the base metal component 81, and a screw portion 96 that is screwed to the screw portion 95 of the base metal component 81 is formed on the peripheral portion of the light source side metal component 82.

Thus, even when a screwed structure is used as the heat conduction connecting means, heat conduction can be efficiently performed from the substrate mounting portion 39 side to the base portion 38 side.

Note that the lamp device main body 34 may be divided vertically by a dividing line in the height direction passing through the center of the lamp device main body 34, and these may be coupled by screwing or the like. In this case, the substrate attachment portion 39 side and the base portion 38 side are integrated as a heat conduction connecting means, and heat can be efficiently conducted from the substrate attachment portion 39 side to the base portion 38 side.

Further, by attaching the lamp device 14 to the socket device 13, the contact surface 41 of the base portion 38 of the lamp device 14 is configured to be in close contact with the instrument main body 12 so as to be able to conduct heat. In this case, an opening is formed in the instrument main body 12 corresponding to the position of the lamp pin 44 of the lamp device 14, and the socket device 13 is arranged facing the opening, so that the lamp pin 44 does not contact the instrument main body 12. The socket device 13 can be mounted.

And since the board attachment part 39 side and the base part 38 side are integrated as a heat conduction connection means, heat conduction can be efficiently conducted from the board attachment part 39 side to the base part 38 side.

The heat conducted to the base part 38 is efficiently conducted to the instrument body 12 with which the contact surface 41 of the base part 38 comes into contact, and can be radiated efficiently.

Note that the lighting circuit 37 may be disposed together with the LED 35 on the lower surface side of the lamp device body 34. In this case, the lamp device main body 34 does not need to be provided with the accommodating portion 40 for accommodating the lighting circuit 37 or is formed separately, and the lamp device main body 34 can be simplified.
